Description of the Related Art Conventionally, as a piping duct, as shown in FIG. 7, a refrigerant pipe provided between an indoor unit and an outdoor unit of an air conditioner is housed along an outer wall of a building to protect the piping. There are things that improve the aesthetics. This duct is made of a resin such as hard vinyl chloride and has a substantially cylindrical shape having a base A having a bottom surface and both side surfaces and a cover engaging over both side surfaces of the base A, and having a predetermined length. For example, those having a length of 2 m are used by connecting them in the longitudinal direction.

That is, since a dedicated base and a cover are separately required to branch the pipe in the duct to the outside of the duct, the number of parts increases, and the assembly at the time of construction and the parts as shown in FIG. Extra work is required for waterproofing the joints between them, so-called caulking.

る。The branch connecting member of the pipe in the duct is made of a resin such as hard vinyl chloride and is formed to have a substantially semi-cylindrical shape. The length in the axial direction is set to, for example, 15 cm, and is disposed between adjacent ends of a plurality of ducts extending in the longitudinal direction. The duct is a duct for accommodating and protecting the refrigerant pipe of the air conditioner as in the related art. That is, using a resin such as hard vinyl chloride as a material, a base A including a bottom surface Aa and both side surfaces Ab and Ab, and both side surfaces Ab and A of the base A
and a cover that engages with b.

The pair of opposing pieces 1, 1 have substantially the same cross-sectional shape as the side surfaces Ab, Ab of the base A, and the same cover that engages with the base A is engaged. The connecting piece 2 connects the pair of opposing pieces 1 and 1 at substantially the same interval as between the side surfaces Ab and Ab of the base A, and has an insertion hole 3 in the center for branching a pipe in the duct out of the duct.

する。With this configuration, the conventional branch cover is not required. That is, since only one cover needs to be engaged with both the base A and the branching connection member, it is possible to save the trouble of separately arranging the branching cover, thereby reducing the man-hour during construction. In addition, since there is no seam between the cover and the branch cover, the seam to be coked is reduced by that much, and the labor required for coking is reduced. Further, when the side edge of the side surface Ab of the base A is brought into contact with the side edge of the opposing piece 1 of the branching connection member, the two are flush with each other, and one cover is engaged therewith. Since the branching connection member does not appear to bulge out at the connection portion of the duct, and becomes less noticeable in appearance, the appearance is improved.

It is formed to have a length of m, but depending on the situation at the site of use, one or both of the base A and the cover may be cut with a metal saw or the like to obtain a desired length. There are cases. For example, if the base A is cut, burrs remain on the cut edge, which is very unsightly. In addition, since accurate cutting is not performed, a gap is generated between the side edge of the opposing piece 1 of the branch connection member and the side edge of the side surface Ab of the base A, and it is possible to abut both without a gap. Can not.

向片1 に着脱可能となっている。Therefore, a concealing piece 4 is provided at a side end of the opposing piece 1. The concealing piece 4 is such that the opposing piece 1 is the side Ab of the base A.
And conceal the seam when connected in the longitudinal direction,
It is made of the same material as the opposing piece 1, but is provided separately from the opposing piece 1. The concealing piece 4 includes a mounting portion 5 for holding the side end of the facing piece 1 and a contact portion 6 that is provided continuously from the mounting portion 5 and abuts against the outer surface of the base A of the duct. It is removable.

Manufacturing efficiency is improved. That is, if they are separate, base A
Is processed by a simple technique such as cutting or drilling
And the connecting piece 2 can be formed, and the concealing piece 4 can be molded with a small and simple mold.However, if the concealing piece 4 is integrated, the base A cannot be used, and the This is because a large and complicated mold is required.

By being detachable from the opposing piece 1, it can be attached to the opposing piece 1 as necessary,
Side surface Ab of base A having substantially the same cross-sectional shape as opposing piece 1
Can be attached to the device, improving usability.
In particular, when the concealing piece 4 is attached to the facing piece 1,
6 can be used as a positioning guide for the base A. The concealing piece 4 may be fixed using a double-sided tape or the like.

At this time, the connecting member for branching is placed on the base such that the insertion hole 3 overlaps the through hole provided on the outer wall of the building.
A, and the side edge of the side surface Ab of the base A abuts against the side edge of the opposing piece 1 of the branching connection member, and the opposing piece 1 of the branching connection member and the side surface Ab of the base A extend in the longitudinal direction. Keep it connected. Here, the contact portion 6 of the concealing piece 4 is
The positioning guide of the base A facilitates the work of arranging the base A. Further, in some cases, the base A is cut, and burrs remain on the end face, or the end face of the branch connecting member cannot be abutted without a gap,
Since the small concealing piece 4 covers the seam, even if the base A is cut, the aesthetic appearance is not impaired.

処理は不要となる。Next, the refrigerant pipe is housed in a duct. At this time, the pipe that needs to be branched is drawn into the room through the insertion hole 3 of the connecting piece 2 and the through hole of the outer wall.
Then, the cover is disposed so as to engage with both the base A and the branching connection member. That is, it is not necessary to dispose the base cover and the branch cover. Thereafter, as shown in FIG. 6, a joint between the base A and the branch connecting member, a joint between the base A and the outer wall,
A caulking process is applied to the joint between the base A and the branch connecting member and the cover. However, since the branch cover is omitted, the caulking process of the joint between the branch cover and the cover is unnecessary.
